Dassey, the nephew of “Making a Murderer” convict Steven Avery, was just 17 when he was convicted in connection with the 2005 murder of photographer Teresa Halbach. He, along with Avery, was sentenced to life in prison for the murder.

An interview with authorities, in which Dassey described gruesome events surrounding Halbach’s murder, was a major sticking point for many “Making a Murderer” viewers. Dassey later retracted his statements.

Shortly after his conviction, Dassey told Wisconsin news outlet the Post-Crescent, “They just kept, like, asking the questions over and over until they got the answer [they wanted].” Some “Making a Murderer” viewers regarded Dassey as a not-particularly-bright teenager manipulated by authorities.

Avery, who has maintained his innocence in Halbach’s death, is currently making a bid for his freedom. While online petitions calling for his pardon were ultimately unsuccessful, he has retained a new attorney, Kathleen Zellner, who specializes in wrongful convictions. Zellner has cited “new evidence” in the case, and said that she is “confident that Mr. Avery’s conviction will be vacated.”

“We are continuing to examine every aspect of Mr. Avery’s case and all of his legal options,” Zellner said in a statement in January. “We are confident Mr. Avery’s conviction will be vacated when we present the new evidence and results of our work to the appropriate court.”

Ken Kratz, who prosecuted Steven Avery, sent TheWrap a nine-point list that he said indicated Avery's guilt, including his claim that Avery "targeted" victim Teresa Halbach.

A White House petition calling for Avery's pardon reached 100,000 signatures, the threshold qualifying it for a White House review. However, the possibility of a presidential pardon was quickly shot down, as the president is constitutionally barred from pardoning convicts in state cases.

A 2009 court filing emerged with a bombshell accusation by Avery -- that his brothers Charles and Earl Avery may have killed Halbach.

Avery has retained a new attorney, Kathleen Zellner, who specializes in wrongful convictions. In a statement obtained by TheWrap, Zellner cited "new evidence" in the case and says that she's "confident Mr. Avery’s conviction will be vacated."

Avery filed a new appeal, claiming that a juror tainted his jury by repeatedly claiming that Avery is "fucking guilty." Avery also asserts that he received "inadequate assistance" from his trial and appellate lawyers.

Attorney Len Kachinsky, whose representation of Avery's nephew Brendan Dassey drew heavy criticism from "Making a Murderer" viewers, told TheWrap that he's "not responsible for Dassey going to prison," adding, "You can say I made a mistake, that I should’ve [attended] or I should have rescheduled the interview — that’s valid criticism.”

Dean Strang, one of Avery's defense attorneys, told TheWrap that a "mass" of potential new evidence has emerged since the premiere of "Making a Murderer."

"Making a Murderer" filmmakers Moira Demos and Laura Ricciardi appeared on the "Late Show With Stephen Colbert" to assert that Avery is "not guilty," with Demos opining, "I mean there are things that he could be guilty, but is he guilty beyond a reasonable doubt? Nothing I’ve seen, and I’ve seen a lot of stuff, nothing I’ve seen has convinced me of that.”

The "Making a Murderer" filmmakers also said that one of the jurors in the Avery trial has come forward to say they believe he is innocent.
